<h2 id="cpu-主频核心缓存"><a class="header" href="#cpu-主频核心缓存">CPU 主频，核心，缓存</a></h2>
<p>主频表示的是CPU的时钟频率，时钟频率越高，当然指令处理的越快。</p>
<p>核心表示是并发处理能力，目前CPU都是1 core 1 processor 和 1 core 2 processor。每个线程(processor)都能单独执行程序</p>
<p>主频是作用于整个CPU的，主频高，每个processor执行的就快。</p>
<p>相同的价位可以获取不同类型的&lt;主频，核心&gt;CPU,主频高点，核心少点，主频低点，核心多点。该如何抉择呢? 这要看具体的工作是什么了，如果是办公或者需要大量并行图形渲染的工作来说，当然是选择核心多，主频低型的CPU，如果是玩游戏这种单一任务，但是需要强大的计算能力,这就适合选择主频高，核心少型的CPU(当然不能太少，最起码得是2核4线程或者4核4线程的)</p>
<p>简单的对主频分一下类: &gt;= 3.6GHz可以看作高端CPU,可以用来流畅的玩各种游戏, &lt; 3.6GHz可以看作中低端CPU,适合作为办公使用。
核心就按照 4核/4线程来作为分界线吧</p>
<p>缓存虽然也是一个重要的参数，但是主频和核心选好了，缓存配套的应该也不会差。只有当价格差不多，主频和核心一致时，才拿缓存这个参数来说事吧。</p>
<h2 id="intel-cpu系列"><a class="header" href="#intel-cpu系列">Intel CPU系列</a></h2>
<ul>
<li>Xeon 志强 主要用于服务器，性能最好</li>
<li>Core 酷睿 酷睿是中高端定位 主要用于台式机和笔记本</li>
<li>Pentium 奔腾 入门级定位，主要用于台式机和笔记本</li>
<li>Celeron 赛扬 低端定位，主要用于台式机和笔记本</li>
<li>Atom 凌动 主要用于移动平台，功耗小</li>
</ul>
<h2 id="intel-cpu后缀"><a class="header" href="#intel-cpu后缀">Intel CPU后缀</a></h2>
<p>有后缀的CPU大部分都是笔记本使用的CPU.</p>
<ul>
<li>M代表标准电压cpu是可以拆卸的</li>
<li>U代表低电压节能的，可以拆卸的；</li>
<li>H是高电压的，是焊接的，不能拆卸；</li>
<li>X代表高性能，可拆卸的；</li>
<li>Q“Q”是“Quad”的缩写，即四核CPU；</li>
<li>Y代表超低电压的，除了省电，没别的优点的了，是不能拆卸的；</li>
</ul>
<p>两个字母的，属于上面这些字母的组合，比如：HQ，表示高电压四核CPU。</p>
<p>M：笔记本专用CPU，表示标准电压双核移动版本。一般为双核，M前面一位数字是0，意味着是标准电压处理器，如果是7，则是低电压处理器。</p>
<p>U：笔记本专用低电压CPU，主要用在超级本上，主频很低且一般为双核处理器。U前面一位数字为8，则是28W功耗的低压处理器（标准电压双核处理器功耗为35W），若前一位数字为7，则是17W功耗的低压处理器，若为0，则是15W功耗的低压处理器。</p>
<p>QM、MQ（QM是三代以前包括三代四核i7的后缀，到第四代QM改为MQ）：笔记本专用CPU，“Q”是“Quad”的缩写，即四核CPU。若QM前一位数字是0，则表示此产品为功耗45W的标准电压四核处理器，若为2，则表示此产品为35W功耗的低电压四核处理器，若为5，与对应为0的CPU主要规格相同，但集成的核芯显卡频率更高（如3630QM和3635QM，后者核显最大频率1.2GHz，前者则是1.15GHz）。</p>
<p>HQ：这个后缀表示CPU核显加强且核心不是一般的Haswell。HQ是四核焊接版，Q是英文“Quad”的缩写，意思是四，代表四核。第四代CPU新出现的系列，主要参数和标准的四核CPU一致，但集成了性能空前强大的核芯显卡Iris Pro5200系列，这种核显的性能可以直接媲美中端独立显卡。目前有i7 4750HQ，4850HQ和4950HQ三款CPU，后来出了一款i7 4702HQ，并没有集成高性能核芯显卡，是定位较为模糊的一款产品。</p>
<p>XM：XM是笔记本旗舰四核i7的后缀，是最强大的笔记本CPU，功耗一般为55W。有这个后缀的笔记本i7相比MQ或QM版本多了2MB三级缓存并支持自由超频技术。“X”意为“Extreme”，此类型CPU完全不锁频，在散热和供电允许的情况下可以无限制超频，而即便是默认频率下，也比同一时代的其它产品强大得多。这类CPU都是工厂生产后精心挑选出来得极品，质量极佳，性能完美，但价格非常昂贵。一块XM系列的CPU批发价可达1000美金以上（普通的四核大概3，400美金一块）。</p>
<p>PM：这个后缀表示CPU没有核显</p>
<p>台式CPU标准款一般没有后缀字母，若有后缀字幕“K”，则是可以超频的版本，若有后缀字幕“X”，则是顶级的至尊版（台式机至尊版CPU为6核心12线程）。</p>

<p>Nvidia (N卡): GTX系 与 RTX系 Titan RTX系
AMD (A卡): R7,R9,RX</p>
<p>N卡GTX系，RTX系与Titan RTX系区别:</p>
<p>GTX代表高端或顶级显卡，原来还有更低级系列的，只是现在没有了，但是10系列还是沿用了GTX。</p>
<p>到了20系列，显卡引入光追新技术，所以GTX改名成RTX，RT即ray tracing(光线追踪)，来表示显卡的光追功能。</p>
<p>Titan RTX算是RTX的一个分支吧，主要在工作站上使用，和RTX系使用相同的图灵架构，但是参数上加强了，Titan系代表当今最强显卡。</p>
<p>N卡Ti和Super后缀的区别:</p>
<p>同一系列Ti后缀的是最强版本，然后阉割一下变成Super版本，Super与Ti差别不是很大，然后再阉割一下就变成没有后缀的版本了。Ti版本才是本体，后边的只是降低性能，适应不同价位的市场。如GTX1660Ti,GTX1660Super,GTX1660。GTX1660Ti性能上非常接近RTX2060卡，但是差了一个光追功能。</p>
<p>买显卡主要看型号，显存和显卡核心频率等参数都是和型号相关的，型号是高端的，显存自然就大，频率就高。这里以一个大概2000价位的中高端显卡GTX1660Ti系来作为比较基线吧
参数名      | 参数
------------|--------------
显卡型号    | GTX 1660 Ti
核心代号	| TU116-400
制造工艺(nm)| 12nm
流处理器/RT核心/Tensor核心|1536/0/0
核心频率(MHz)|1500
加速频率(MHz)|1770
显存位宽(-bit)|192
显存容量|6GB GDDR6
显存频率(GHz)|12
整卡功耗(W)|120</p>
<p>这里说一下显存类型，显存是基于内存改造的，如GDDR5显存是基于DDR3内存改造而来，GDDR6基于DDR4内存技术。</p>
<h1 id="内存条"><a class="header" href="#内存条">内存条</a></h1>
<h2 id="ddr3-ddr4-ddr5"><a class="header" href="#ddr3-ddr4-ddr5">DDR3 DDR4 DDR5</a></h2>
<p>DDRx x表示的是第几代内存条，如DDR4就是第4代内存条，每一代频率都会分为3个档次,以DDR4为例频率主要2666、3200、3600三种，性价比最高的是3200MHZ</p>
<h2 id="8g--2-与-16g"><a class="header" href="#8g--2-与-16g">8G * 2 与 16G</a></h2>
<p>结论就是两条8G内存条要比一个16G内存条性能好，因为是双通道访问.</p>
<h1 id="主板"><a class="header" href="#主板">主板</a></h1>
<p>主板主要是和CPU适配，主要是intel CPU, intel CPU的插槽类型最多变。下面是一个简单的表格,展示的Intel 最近系列的CPU使用的插槽类型。</p>
<table><thead><tr><th>插槽</th><th>CPU系</th></tr></thead><tbody>
<tr><td>LGA1200</td><td>全11代，大部分10代。以后不用了</td></tr>
<tr><td>LGA2066</td><td>小部分10代</td></tr>
<tr><td>LGA1151</td><td>9代，8代</td></tr>
</tbody></table>
